I’m sorry, I don’t understand your Q. Employers pay premiums for workers and the WCB pays health benefits if workers get injured. It’s basically an insurance scheme. Not sure if your Q is how long must WCB pay health benefits or how long must employer pay premiums if worker gets injured. If it’s the former, it depends on a whole bunch of complex factors; if it’s the latter, I believe the answer is that premiums must be paid for as long as a worker is on the active payroll. If this doesn’t help, pls feel free to loop back with me. glennd@bongarde.com
